73 <br />it Mn <br />To: Mark Bernhardson, City Administrator coui+ ETING 218.1 <br />PROM: Jeanne A. Mabusth, Zoning Administrator MAR 2 819eB <br />DATE: February 18, 1988 <br />MY AF Qt1t2 <br />SOBJ: Geo Textile Fabric - Presentation by City E g'i at Council <br />Meeting of February 22, 1988 <br />Mike Lynch, from Bonestroos office, presented information and samples of <br />geo textile fabrics before the Planning Commission at their February 16, <br />1988 meeting. Lynch confirmed that if a fabric and appropriate, adequate <br />stone cover is provided, the surface is more permeable than grass in bed of <br />clay soils. As for control of weeds, Lynch noted grass shoots will manage <br />to weave through the fabric but certainly the system will provide a desired <br />level of weed control. Staff feels this is a more acceptable way to the <br />control of weeds than the using of chemicals. <br />The concern of the majority of the Planning Commission was the suggestion <br />that the areas installed with a permeable geo textile fabric system not be <br />considered as hardcover. Planning Commission felt enforcement problems <br />would outweigh the positive aspects of the policy, feeling the enforcement <br />demands would be a strain for the limited existing inspection staff of the <br />City. Planning Commission asked how the City could maintain an <br />inventory/record and provide routine inspections of all approved geo <br />textile areas classified is non -hardcover -- and the means by which the <br />City could insure that contamination of the permeable system does not <br />occur? <br />Glenn Cook will make a similar presentation to the Council at your February <br />22nd meeting providing information on the many different types and uses of <br />these fabrics. Note that it is a specific geo textile fabric that is used <br />with the fabric stabilized enbankment system recently recommended by the <br />engineering staff for properties with severe eroding steep lakeshore banks. <br />Staff Recommendation - To continue to recommend the use of the fabrics in <br />the control of weed growth and stabilization of banks and to delay adopting <br />a policy that would define the permeable geo textile fabric system used in <br />landscaping as non -hardcover until the City staff can present a system of <br />permitting, inspecting, and enforcement that would provide the necessary <br />controls for lakeshore properties with excess hardcover for Council's <br />review, amendment and action. <br />TO: Mayor Grabek and Councilmembers <br />FROM: Mark Bernhardson, City Administrator <br />Forwarded recommending approval. <br />PROPOSED MOTION: Moved by _, seconded by _, that the City Council allow <br />the continued use of geo textile fabric in the control of weed growth and <br />stabilization of banks and to delay adopting a policy that would define the <br />permeable geo textile fabric system used in landscaping as non -hardcover <br />until the City staff can present a system of permitting, inspecting, and <br />enforcement that would provide the necessary controls for lakeshore <br />properties with excess hardcover.
